ABSTRACT

A method of setting up, caring for and later removing a temporary rasta hairstyle is described. This method includes one or more of the following steps: applying a roughness-increasing substance to the hair to roughen the hair, applying an adherence-increasing substance to the hair to increase adherence of hairs to each other, and subsequently setting up the temporary rasta hairstyle by intertwining hair strandwise. The cleaning of the temporary rasta hairstyle occurs preferably using a concave sponge, without disturbing the temporary rasta hairstyle. To again remove the temporary rasta hairstyle a composition that increases the combability is applied to the hair and the rasta strands are opened and unwound or untwisted. Multi-component kits and compositions for performing the method are also described.

BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention relates to methods for setting up, caringfor and later removing a temporary rasta hairstyle, to compositions andingredients used in the methods and to multi-part kits for performingthe methods.

[0004] 2. Description of the Related Art

[0005] A permanent rasta hairstyle is a hair fashion comprising tightlybraided long braids usually comprising thin and extremely stronglyinterlocked hair strands. These types of hairstyles are also calleddreadlocks. Both names are used synonymously in the followingdescription. Ethnic hair (e.g. African or Afro-American hair, so-calledkinky hair) is ideal for setting up dreadlocks or rasta hairstylesbecause of its naturally curliness and its nature. However rastahairstyles can be set up with other, among others, smooth, hair, such asmiddle European or Asiatic hair, with suitable techniques. It isnecessary however to produce a hair structure that tends to facilitatestrongly interlocking the hair strands prior to forming the locks. Thisusually occurs by a combination of chemical and mechanical treatments ofthe hair. First it is necessary that the hair is made dull. Hair flakeor scale should not be present on the hair shaft, but should be removedas much as possible. The chemical treatment can occur with a hairreducing agent (e.g. thio compounds, such as thioglycolic acid), such asis used in a permanent wave treatment, but with the difference that theeffective concentration and/or action is greatly increased. During thislatter treatment the cuticle layer is probably at least partially orentirely removed to increase the required tendency of the hair strandsto interlock. Another chemical treatment is an alkaline treatment withstrong alkali compositions, e.g. corn soap or an alkaline shampoowithout care additives. Furthermore an intense mechanical treatment ofthe hair is required to remove the flake or scale. This can occur by anintense “toupier” of the hair as strong as possible for several hourswith a very fine comb, e.g. with a lice comb or similar comb, usuallywith stable metal teeth. “Toupier” of the hair is also called“back-combing”. These terms are used synonymously in the following.During back-combing there is an intense irreversible interlocking of thehair and the hair is irreparably damaged. Another problem besides hairdamage is that the rasta hair style is permanent when set up with theconventional hair techniques and is not removable. The interlocking ofthe hair is irreversible, i.e. it cannot be reversed without more. Thosewho set up this hairstyle once only remove it by cutting off the hairwith a scissors. Some fashion-conscious users would like to have a rastahairstyle only temporarily or only for a certain occasion, e.g. for aparty on the weekend, and would like to switch back to their originalhairstyle the next day without damaging their hair. Thus there is astrong demand for a removable temporary rasta hairstyle that does notentail damaging hair treatment steps. An additional problem with theconventionally set up rasta hairstyle is hygienic. There is thus a needfor cleaning strongly interlocked hair strands, which is currentlydifficult or not possible. There is thus a danger that the interlockedhair strands can come apart from within, can be damaged and even breakoff or fall out. Thus for the user, who wants to have a rasta hairstylefor a long time, a method is thus desirable, which permits the openingor separation of the strands after a certain time. Thus the desiredrasta hairstyle can be set up anew after an intense hair cleaning and/orhair care treatment.

SUMMARY OF THE INVENTION

[0006] It is an object of the present invention to provide a method ofsetting up a temporary rasta hairstyle, which does not suffer from theabove-described disadvantages and which can be removed later withoutdamaging the hair.

[0007] It is a further object of the present invention to providecompositions for effectively performing the method of setting up atemporary rasta hairstyle according to the invention.

[0008] It is another object of the claimed invention to provide amulti-part kit for the method of setting up a temporary rasta hairstyleaccording to the invention.

[0009] It has now been found that these objects can be surprisinglyattained by a method according to the invention of setting up atemporary rasta hairstyle and later removing it.

[0010] According to the invention this method includes one or more ofthe following steps:

[0011] a) applying one or more roughening substances to the hair toincrease the roughness of the hair surface or applying at least onecomposition making back-combing easier;

[0012] b) applying one or more adhesion-increasing substances to thehair to increase adherence of hairs to each other; and

[0013] c) setting up temporary rasta strands by intertwining the hairstrand-wise, without essentially, i.e. irreversibly, interlocking thehairs.

[0014] The intertwining of the hair strands can occur e.g. either bygently back-combing or by one or more of dividing, drawing apart andtwisting the divided hair strands, or by a combination of twisting thestrands around their long axis and gently back-combing the twistedstrands. The cleaning of the temporary rasta hair style can occur usinga concave sponge, without destroying the hair style. In order to removethe temporary rasta hairstyle another composition, which increases thewet combability of the hair, is applied to the hair. The rasta strandsare opened and/or unwound, preferably mechanically using an ordinarycomb or brush.

[0015] It was surprisingly found that it is possible to produce anauthentic or an at least nearly authentic rasta-look or rastaappearance, like a “true” permanent rasta, without damaging the hair andwithout the up to now strongly irreversibly interlocked hairs consideredas a prerequisite. Furthermore it was surprising that the removal of therasta hairstyle is possible simply without problems. The hair makes aneven better cared for and healthier impression than prior to treatmentafter removal of the temporary rasta hairstyle, especially regarding thefeel, luster and combability. This is immediately astonishing, since upto now a rasta hair style is almost synonymous with strongly damaged anduncared for hair. Now with the methods according to the invention theopposite has been achieved. The care action is partially what one wouldhave expected from the action of the remover composition C that isdescribed in detail hereinbelow. This means that it is based on asynergistic care action of the remover composition C in combination withthe pre-treatment compositions A and/or B described in more detailbelow.

[0016] The subject matter of the invention is thus a method of settingup a temporary rasta hairstyle, in which, prior to or after putting thehair in the hairstyle, at least one of the following process stepsoccurs: (1) applying to the hair surface at least one rougheningsubstance for roughening the hair surface or at least one compositionfor making back-combing of the hair easier and (2) applying to the hairtips or the hair at least one substance increasing adherence of thehairs to each other. The term “temporary rasta hairstyle” means ahairstyle with the appearance of a rasta look, which is again removablein contrast to a permanent rasta hairstyle. In contrast to the permanentrasta hairstyle the hair is not essentially or substantiallyinterlocked, but only intertwined, i.e. the hairs that are twistedtogether can be mechanically separated from each other again. Theroughening substance that increases the roughness of the hair surface isa substance, which adheres to the hair surface and causes clean hair tofeel rough or dull in contrast to hair that has not been treated. Thissubstance can be applied to the hair by means of composition A, which isdescribed in more detail hereinbelow.

[0017] The stability of the temporary rasta hairstyle is clearlyincreased when an adhesion-increasing substance that increases theadherence of the hairs with each other is applied to hair and/or to thehair tips that has or have been pre-treated with the rougheningsubstance increasing the surface roughness. The application of theadhesion-increasing substance increasing the adhesion of the hairs witheach other can occur by means of the composition B that is described inmore detail hereinbelow. The adhesion-increasing substance can beapplied either prior to or after setting up the rasta hairstyle asnecessary.

Setting Up of the Temporary Rasta Hairstyle

[0018] To set up the temporary rasta hair style hairs that arepredetermined according to the invention are arranged or put in one ormore temporary dreadlocks. This can occur by several methods. One of thethree following methods is recommended for doing this. The recommendedmethods are to be understood as exemplary embodiments. In all of thesetechniques the setting up of the dreadlocks begins on the neck. Moreoverone section (for example of about three cm thick) is divided from sideto side transversely to the head. The base surface of the individualdreadlocks (individual strands) depends on the desiredthickeness/density, amounting usually to 6 to 9 cm² and can be square,rectangular, trapezoidal or triangular. One works in the direction ofthe forehead in these methods or techniques. The dreadlocks are laidover each other in the manner of shingles. In order to improve theplaned hairstyle, the dreadlocks are preferably held directly in thedesired direction during setting up of the hairstyle.

Especially Preferred Methods

[0019] The separated individual strand is uniformly gently back-combed(intertwined, not interlocked) with a back-comb from the hair roots tothe hair tips. During the back-combing the individual strand is twistedover its long axis, whereby a special round and “true” appearingdreadlock is produced. Instead of a back-comb also any suitable tool,for example a brush or currycomb with bristles, teeth or prongs made ofmetal, hard plastic or the like can be used.

Additional Preferred Methods

[0020] The separated or divided individual strand is strongly twistedwith the fingers over its long axis. After 2 to 3 twists the hair strandis arbitrarily divided at the tips. Both hair strands arising by thedivision are now spread from each other, whereby the two to three priortwists move toward the hair roots and intertwine (similar to backbombing). The twist, division and spreading of the hair strand isperformed until the entire length of the individual strand isintertwined.

Additional Possible Methods

[0021] The separated or divided individual strand is strongly twistedwith the fingers over its long axis, until the entire strand iseffectively “knurled”. The hair tips of the hair strand are held fixedand the spreading on the long axis is somewhat reduced. Now the alreadytwisted strand is gently back-combed with a suitable back-comb, withoutinterlocking the hairs. The back-combing occurs over the entire axiallength of the individual strand. After that the twisted and back-combedstrand is rolled between the thumb and index finger once more in orderto augment the intertwining effect.

Composition A

[0022] The application of the roughening substance increasing theroughness of the hair surface can occur by means of a first compositionA (A1, A2). Suitable substances are e.g. those substances, which aresolid at room temperature (25° C.) and are present in the form ofparticles. Silica, silicates, aluminates, clays, micas, salts,especially inorganic metal salts, metal oxides, e.g. titanium dioxide,minerals and polymers are somewhat suitable. Polymers, which impart arough dull feel to the hair, are suitable. The suitability of a polymeris established by half-side tests of polymerically treated hair incontrast to untreated hair.

[0023] Suitable roughening polymers are, for example, copolymers ofalkylacrylamides, especially C₁-C₈-alkyl groups, and at least onemonomer selected from the group consisting of acrylic acid, methacrylicacid and their simple esters, especially the C₁-C₄-alkyl esters (INCI:acrylates/octylacrylamide copolymer, acrylates/t-butylacrylamidecopolymer, e.g. AMPHOMER® HC and/or ULTRAHOLD® 8); copolymers of vinylmethyl ether and alkyl hemiesters of maleic acid, especially C₁-C₅-alkylhemiesters (INCI: butyl ester of PVM/MA copolymer, e.g. GANTREZ® ES 425;copolymers of vinyl acetate and crotonic acid (INCI: VA/crotonatescopolymer, e.g. LUVISET® CA 66).

[0024] The roughening substance can be present in the form of solidparticles in the composition A and preferably the solid particles aredispersed in the composition to form a stable dispersion. Alternativelythey can be present in dissolved form in a suitable cosmeticallyacceptable solvent. They are then separated from the solution afterapplying the solution to the hair and evaporating the solvent. A stabledispersion can be attained, when the composition A is provided with aflow limit, which is sufficiently large, in order to prevent thesettling of the solid particles. This flow limit can be adjusted to asuitable value by using a suitable gel former.

[0025] Silica (silica gel, silicon dioxide) and metal salts, especiallyinorganic metal salts, are especially preferred as the rougheningsubstance applied to the hair. Silica is most preferred. The metal saltsinclude, e.g., alkali or alkaline earth metal halides, such as sodiumchloride and potassium chloride; alkali or alkaline earth sulfates, suchas sodium sulfate or magnesium sulfate. In the event that a solublemetal salt is used composition A is preferably an aqueous solution ofthis salt and is preferably in combination with a spraying device, e.g.a mechanically operated spray pump. In case insoluble particles areused, which are not soluble in water, alcohol and/or an alcohol/watermixture, such as silicon dioxide or a metal oxide, composition A ispreferably a gel having a flow limit or yield point and contains atleast one gel former that establishes the flow limit. Alternativelycomposition A is a foamable composition containing at least onefoam-forming surfactant and/or foam-forming polymer. The foaming canoccur by an aerosol propellant or by means of a mechanically operatedapparatus for making foam.

[0026] In the case of the embodiments of composition A that are gel,thickening polymers are included, which impart a plastic orpseudo-plastic behavior to the compositions. The rheological flowproperties of the gel according to the invention are characterized bythe existence of a flow limit. The flow limit preferably amounts to atleast 3 Pascal, measured with a Haake Rotation Viscometer RV 12,measurement system PKV-0.5 at 30° C. and at a linearly increasing shearrate of 0 to 100 s⁻¹. After exceeding the flow limit the gel preferablyhas a viscosity of 1,000 to 100,000 mPa.s, especially from 5,000 to50,000 mPa.s at 25° C., measured with a Haake Rotation Viscometer TypeVT 501 at a shear rate of 12.9 per second. The flow point or flow limitis selected according to weight and surface area of the particles sothat it is at least as large as the pressure exerted by the particles.The settling of the particles is thereby prevented. The thickeners arepreferably contained in an amount of from 0.05 to 10, especiallypreferably from 0.1 to 4, percent by weight, in composition A. Theoptimum concentration is dependent on the type of thickener and theweight of the particles. Suitable thickeners are cross-linked or notcross-linked polyacrylic acids or polymethacrylic acids. Thesethickeners, which can be contained in the compositions according to theinvention, include homopolymers of acrylic acid with a molecular weightof 2,000,00 to 6,000,000 g/mol, which are marketed e.g. by Goodrich, USAunder the trademark CARBOPOL®. Additional thickeners are e.g. theacrylic acid polymers, acrylic acid/acrylamide copolymers or SclerotiumGum, marketed under the trademark MODAREZ® V 600 PX of Protex, France orunder the trademark CARBOPOL® ETD 2001 by Goodrich, USA. Copolymers ofacrylic acid or methacrylic acid, such as those marketed under thetrademark CARBOPOL® 1342 or PEMULEN® TR1 of Goodrich, USA, are suitable.Guar gum, xanthan gum, bentonite and hectorite are additional suitablethickeners. In an advantageous embodiment of the composition thickenersare included in the composition besides those that impart a sufficientflow limit or flow point in the viscosity range typical for gels inaddition to those thickeners that impart a sufficient flow limit or flowpoint to the composition. These latter thickeners include especiallycellulose and cellulose derivatives, such as carboxymethyl cellulose,cellulose ether and hydroxyalkyl cellulose compounds, such as tohydroxyethyl cellulose and hydroxypropyl cellulose. The thickenerscontain acid groups, which are at least partially neutralized withcosmetically compatible bases. Suitable organic or inorganic bases thatare appropriate for cosmetic applications can be used as theneutralizing agents. For example, the bases can include amino alcohols,such as aminomethylpropanol (AMP), triethanolamine or monoethanolamineand ammonia, NaOH and others.

[0027] Composition A also can be in the form of an aerosol ornon-aerosol sprayable or foamable product. The aerosol products includea pressure-tight aerosol container with a spray or foam head, whichcontains the foamable or sprayable composition. The pressure-tightaerosol container of the aerosol spray product according to theinvention can be made from any material known for aerosol spray or foamproducts. Metals, such as aluminum or tin, are especially suitablematerials. Preferably the aerosol propellants are employed in an amountof from 1 to 20, especially preferably from 2 to 10, percent by weight.For example, lower alkanes, such as n-butane, i-butane, propane, butane,or also their mixtures and dimethyl ether or fluorohydrocarbons, such asF 152a (1,1-difluoroethane) or F 134 (tetrafluoroethane) are suitable asthe aerosol propellants. In addition, propellants present in compressedgaseous form, such as N₂, N₂O and CO₂, and their mixtures are suitableas the propellants.

[0028] Preferably the composition comprises an aqueous or anaqueous-alcoholic medium with preferably at least 10 percent by weightwater. The solvent system is preferably present in the composition in anamount of 50 to 98, especially preferably from 75 to 95, percent byweight. The alcohols included in the solvent system especially includelower alcohols having one to four carbon atoms that are suitable forcosmetic purposes, such as ethanol and isopropanol. Organic solvents ormixtures of solvents with a boiling point under 400° C. are suitable asco-solvents in amounts of from 0.1 to 15, especially from 1 to 10,percent by weight. Branched or unbranched hydrocarbons, such as pentane,hexane, isopentane and cyclic hydrocarbons, such as cyclopentanes andcyclohexane, are suitable as additional co-solvents. Glycerol, ethyleneglycol and propylene glycol are additional especially suitablewater-soluble solvents.

[0029] In the case of non-aerosol sprays and non-aerosol foams, thecompositions are present in combination with a mechanically operatedapparatus for spraying or forming.

[0030] The foamable products usually contain at least one foam-producingsubstance, e.g. a foam-forming surfactant and/or a foam-forming polymer.The surfactant can have nonionic, anionic or amphoteric character.Nonionic foam-forming surfactants are preferred. The surfactants can beused individually or in a mixture. The amount of the surfactants can bevaried and is selected so that a sufficient amount of foam is formed forworking into the hair, when the composition is delivered from theaerosol container or the product dispenser. The surfactant amount ispreferably typically from 0.01 to 5, especially preferably from 0.1 to2, percent by weight. Suitable nonionic surfactants are, for example,the C₈- to C₁₈-fatty alcohols, which can be ethoxylated with from 8 to45 mol ethylene oxide, e.g. lauryl alcohol, tetradecyl alcohol, cetylalcohol, oleyl alcohol or stearyl alcohol, ethoxylated with up to 40 molethylene oxide per mol fatty acid, alone or in a mixture; hydrogenatedcastor oil ethoxylated with 8 to 45 mol ethylene oxide; C₈- to C₁₈-fattyacid alkanolamides; fatty alcohols of ethoxylated lanolin orethoxylatedlanolin; polyglyceryl ethers of saturated or unsaturated fatty alcoholsand alkyl phenols with 8 to 30 carbon atoms in alkyl groups and with 1to 10 glyceryl units per molecule; polyethylene/polypropylene blockcopolymers and ethoxylated sorbitan fatty acid ester. Derivatives ofnatural surfactants, e.g. alkylpolyglycosides, are especially preferredas the nonionic surfactants. For example, alkyl sulfates, alkyl ethersulfates, alkyl sulfonates, alkoyl sarcosinates, akly isethionate ordialkylsulfosuccinates, which contain from 8 to 18 carbon atoms, aresuitable anionic surfactants. Betaines are especially suitable asamphoteric surfactants. For example, the betaines include C₈- toC₁₈-alkyl betaines, such as cocodimethylcarboxymethylbetaine,lauryldimethylcarboxymethylbetaine,lauryldimethyl-alpha-carboxyethylbetaine,cetyldimethylcarboxymethylbetaine,oleyldimethyl-gamma-carboxypropylbetaine andlauryl-bis-(2-hydroxypropyl)-alpha-carboxyethylbetaine; C₈- toC₁₈-sulfobetaines, such as cocodimethylsulfopropylbetaine,stearyldimethylsulfopropylbetaine, lauryldimethylsulfoethylbetaine,lauryl-bis-(2-hydoxyethyl)sulfopropylbetaine; the carboxyl derivativesof imidazoles, the C₈- to C₁₈-alkyldimethyl ammonium acetates, the C₈-to C₁₈-alkyldimethyl carboxymethyl ammonium salts and the C₈- toC₁₈-fatty acid alkylamidobetaines, such as coconut fatty acidamidopropylbetaine, and N-coconut fatty acidamidoethyl-N-[2-(carboxymethoxy)ethyl]glycerol (CTFA:cocoamphocarboxyglycinate).

[0031] The back-combing of the hair can also be made easier by treatmentwith compositions, such as corn soap or permanent wave shapingcompositions containing hair keratin reducing compounds. The use ofpermanent shaping means occurs preferably under mild conditions, inwhich the hair is not greatly damaged, e.g. with smaller effectiveingredient concentrations and/or short acting times. The permanentshaping agents contain hair keratin reducing agents, which act byopening the cystine disulfide bridges of the hair keratin. Effectivereducing agents include especially thio compounds, such as salts ofsulfur containing acids or certain mercapto compounds, especially saltsor esters of mercaptocarboxylic acids. The classical permanent shapingagent in the art, namely thioglycolic acid, or its ammonium ormonoethanolamine salt, can also be used in the methods according to thepresent invention. Additional conventional reducing agents are inorganicsulfite, 2-mercaptopropionic acid (thiolactic acid), 3-mercaptopropionicacid, mercaptocarboxylic acid ester, mercaptocarboxylic acid amide,cysteine and derivatives of these compounds. The salts or derivatives ofmercaptocarboxylic acid, especially thioglycolic acid, cysteine andthiolactic acid or their salts, are particularly preferred.

[0032] The permanent shaping effective ingredient can be used in anamount of from 2 to 30 percent by weight. The lower concentrations aregenerally preferred up to a maximum of 20 percent by weight, especiallyup to a maximum of 10 percent by weight.

[0033] One composition can be made available, which is universallysuitable by variation of pH for any hair structure, if necessary withadditional heating action. The composition is adjusted to be eitheracidic (with sulfite, bisulfite and mercaptocarboxylic acid ester) oralkaline (with alkali and ammonium salts of mercaptocarboxylic acid).Alkalizing agents are used to adjust the pH to e.g. 7 to 10, especially7 to 8.5. These alkalizing agents include ammonia, soda lye, organicamines, e.g. monoethanolamine, and also all other water-soluble,physiologically compatible basically reacting, organic or inorganicsalts, such as ammonium or alkali carbonates and ammonium or alkalihydrogen carbonates. In order to adjust the pH of the composition sothat the composition is acidic (e.g. pH=6.5 to 6.9), esters ofmercaptocarboxylic acids, e.g. monothioglycolic acid glycol ester ormonothioglycolic acid glyceryl ester, preferably mercaptoacetamide or2-mercaptopropionic acid amide, in a concentration of 2 to 14 percent byweight; or the salts of sulfur-containing acids, e.g. sodium-, ammonium-or monoethanolammonium sulfite, in a concentration of 3 to 8 percent byweight (calculated as SO₂) can be used.

[0034] The permanent shaping composition used in the methods of theinvention can be present in the form of an aqueous solution or anemulsion as well as in thickened form on an aqueous basis, especially asa cream, gel or paste. It is particularly preferable that it is inviscose form with a consistency that permits the hair to be treated inplace and not, as is common in the art, in a wash basin. A viscosity offrom 100 to 10,000, preferably from 300 to 1000, mPa s at 25° C. isespecially preferred. The stated viscosity limits relate to ameasurement with a Haake Rotation Viscometer Type VT 501 with a shearrate of 64.5 per second. Similarly it is possible to fill thesecompositions in an aerosol can under pressure and to dispense them asaerosol foam.

[0035] A so-called swelling and penetration agent can be included in thepermanent shaping composition to increase its effectiveness. Swellingand penetration agents include, e.g., urea, polyhydric alcohols, ether,melamine, alkali or ammonium thiocyanate, isopropanol, dipropyleneglycol monomethyl ether, 2-pyrrolidone, imidazolidin-2-one or1-methyl-2-pyrrolidone in an amount of about 0.5 to 50 percent byweight, preferably 2 to 30 percent by weight. To avoid overcurling ofhair dithio compounds, especially dithiols, dithiodiglycolic acid,dithiolactic acid, or the respective salts of the dithiols are added.

[0036] During application the hair can be washed with a shampoo andafter that rinsed with water. Subsequently the hand towel dried hair canbe divided into individual strands and only individual strands aretreated when only a partial rasta hair style is to be set up. Then thehair is treated with the agent or composition in a sufficient amount,preferably from 60 to 120 grams. After a sufficient acting time, whichdepends on the hair nature, pH and action of the permanent shapingcomposition, as well as on application temperature, namely from 2 to 30minutes (5 to 30 minutes without heat; 2 to 20 minutes with heating),the hair is rinsed with water. The shorter acting times, for example upto 15 minutes or up to 10 minutes without heating or up to 10 or 7minutes with heating, are preferred.

Composition B

[0037] The application of the adhesion-increasing substance causing thehairs to adhere to each other can occur by means of a second compositionB. Suitable substances are, e.g., waxes, waxy materials and/or adhesivepolymers. Waxes and waxy materials are especially those substances withthe properties according to the definition of waxes in Ullmanns'Encyclopedia of Industrial Chemistry, 4^(th) th Edition, Volume 24, page3. According to this Encyclopedia the waxes are kneadable at 20° C.,solid to brittle and hard, fine to gross crystalline, at leasttranslucent to opaque, however not glassy, melting over 40° C. withoutdecomposition, comparatively low viscosity a little over its meltingpoint, strongly temperature dependent in its consistency and solubilityand polishable under a gentle pressure. In the following the terms “waxsubstance” and “waxy or wax-like substance” are synonymous in thefollowing. Adhesive polymers, which are suitable, include thosepolymers, which impart an adhesive feel to the hair, as established byhalf-side tests of polymerically treated hair in comparison to untreatedhair.

[0038] Suitable hydrophobic waxes include animal, plant, mineral andsynthetic waxes, microcrystalline waxes, solid paraffins, petrolatum,VASELINE®, ozokerite, montan wax, Fischer-Tropsch wax, polyolefin waxes,for example polybutene, beeswax, wool wax and its derivatives, e.g. woolwax alcohols, candelilla wax, carnauba wax, Japan wax, hardened fats,fatty acid esters and fatty acid glycerides with a solidification pointof over 40° C., polyethylene waxes and silicone waxes. The waxes have asolidification point of over 40° C., preferably over 55° C. The needlepenetration number (0.1 mm, 100 g, 5 s, 25° C., according to DIN 51 579)is preferably in a range of from 2 to 70, especially from 3 to 40,especially preferably less than 20. Carnauba wax, ceresin wax and theirmixtures are especially preferred. The waxes and waxy materials incomposition B are preferably contained in an amount of from 4 to 50,especially preferably from 8 to 30, and particularly preferably from 10to 25, percent by weight.

[0039] The composition B containing the adherence-improving substancefor promoting the adherence of the hairs with each other can be presentin various application forms, especially a lotion, gel, aerosol spray,non-aerosol pump spray, aerosol foam, non-aerosol foam product or as asolid or semi-solid wax product in a dish or in the form of a pencil.

[0040] In an especially preferred embodiment composition B is an aqueousemulsion of a hydrophobic wax and contains at least one emulsifier andwater in addition to the wax. The term “emulsion” includes waxdispersions in water, but also suspensions of solid wax particles inwater. The emulsifiers are, preferably, contained in an amount of 0.5 to50, especially from 3 to 40, and particularly from 20 to 35, percent byweight. Preferably the emulsifiers are nonionic surfactants. Thefollowing emulsifiers are especially suitable:

[0041] addition products of 2 to 30 mol ethylene oxide and/or 1 to 5 molpropylene oxide to C₈- to C₂₂-fatty alcohols, to C₁₂- to C₂₂-fatty acidsor to alkanol phenols with C₈- to C₁₅-alkyl groups;

[0042] C₁₂- to C₂₂-fatty acid monoesters or diesters of additionproducts of from 1 to 30 mol ethylene oxide to glycerol;

[0043] addition products of 5 to 60 mol ethylene oxide to castor oil orto hardened (hydrogenated) castor oil; and

[0044] mon-, di- and triesters of phosphoric acid with addition productsof 2 to 30 mol ethylene oxide to C₈- to C₂₂-fatty alcohols.

[0045] In an especially preferred embodiment the total amount of theemulsifiers present is larger than the total amount of the waxes. Thatmeans that the weight ratio of the emulsifier to wax is larger than 1:1,preferably up to 5:1, especially preferably from 1.5:1 to 3:1. Theseembodiments are characterized by a combination of individual activeingredients. Directly after the application to the hair the adhesionforce of the hairs is very high, which very much simplifies the settingup of a rasta hairstyle. After drying the adherence is greatly reduced,which leads to an improved pleasant feel. A reduced, not unpleasant,residual adhesion remains and causes the finished rasta strands toadhere loosely to each other, which provides additional fresh hairstyling possibilities. The preferably advantageous automaticallydecreasing adhesion force is especially strongly expressed incombination with silica as the roughening substance that increases theroughness of the hair. An additional especially advantageous effect isthe sufficiently good residue-less removal of the hydrophobic wax,especially using the composition C described further below for removingthe rasta hairstyle. Composition B is present ideally in liquid, i.e.liquid or viscous form. It is preferably dispensed in liquid form bymeans of a pumping device, sprayed as a spray by means of a sprayingdevice or as foam with an apparatus for producing foam. For additionalingredients for the aerosol and non-aerosol embodiments reference ismade to the similar ingredients described above as suitable forcomposition A.

[0046] As waxes however hydrophilic waxes can be used, especially highmolecular weight polyethylene glycols (PEG). The polyethylene glycolsare preferably waxy solids at room temperature (20 to 25° C.) or atleast soft waxy-like compositions with a solidification temperature atabout 30° C., preferably at about 40° C.
